Kuongorora kukosha kwesimbi furo zvinhu

Metal foam imhando yeporous simbi zvinhu zvinoumba akawanda-dimensional spatial mesh zvimiro musimbi matrix, inozivikanwawo seporous metal foam, iyo yakawana kutariswa zvakanyanya kumba nekune dzimwe nyika nekuda kwekusanganiswa kwayo kwesimbi zvivakwa uye zvimwe zvakakosha zvemuviri. zvinhu zve nonmetals. Mumakore makumi mashanu apfuura, kwave nekufambira mberi kukuru mukuvandudzwa kwesimbi furo, kuvandudza kwekushandisa uye dzidziso yezvidzidzo zvezvimiro zvayo.
Kubatanidzwa kwe "furo" uye "simbi" pfungwa mbiri, hatigoni kubatsira asi kufunga kutifuro resimbizvinhu zvinosanganisa mabhenefiti ezviviri izvi zvinhu: kuchengetedza yakanakisa ductility yesimbi, weldability uye magetsi conductivity panguva imwe chete, nekunyura kwesimba uye kuvhunduka kutorwa, acoustic ruzha kuderedza, kufema uye mvura inopindika, uye zvimwe zvakakosha.
Metal furo zvinhuine simbi skeleton pores, sangano rakanyanya inhomogeneous, kana ichiiswa kunze kwekumanikidzwa, kune matatu deformation matanho, anoti, elastic deformation nhanho, brittle kupwanya nhanho uye compact nhanho, saka kana iyo simbi furo zvinhu zvichikanganiswa, strain zviri pachena kuti yasara kuseri kwekushushikana, mustress-strain curve ine nguva yakareba yenzvimbo yebani. Haisi kungokwanisa kutora simba rakawanda, asi zvakare inokwanisa kuramba yakakwira inoparadza kushushikana, chinhu chine yakanakisa kukanganisa kupikisa. Zvinonzi density ratio ye 0.05 ~ 0.15 yealuminium furo inogona kutora simba re20 ~ 180 MJ / m2. Kushandiswa kwayo yakanakisa kukanganisa kupikisa, kuitira kuti iyoaluminium foaminogona kushandiswa sebhampa yemotokari, giya rekumhara remuchadenga, macushion ekuchengetedza erevheta, akasiyana mabhokisi ekurongedza, pamwe nemaroketi neinjini dzejeti, zvinhu zvekudzivirira. Metal foam inowanzowanikwa pakati pesangweji yemahwendefa maviri ekuvhundutsa kunyura uye aesthetic zvinangwa.
Zvinei kune mamwe marudzi emidziyo yeporous, simbi furo ine yakanaka conductivity yemagetsi, iine humwe hunhu hwekuzvitsigira uye mabhenefiti enzvimbo yakakura yekupa nzvimbo yakafararira yekemikari yekuchaja yekufambisa nzvimbo, porous foam electrode chimiro chinogona kuvandudza zvakanyanya porosity ye. iyo electrode, inogona kuzadzwa nezvimwe zvinhu zvinoshanda, wedzera huwandu hwebhatiri kuitira kuti electrode yeiyo chaiyo density ideredzwe zvakanyanya pakudzidza kweyakanyanya simba simba, hupenyu hurefu, Lightweight bhatiri electrode zvinhu. kupa mukana. Saka, furo resimbi rinova rakanakisa electrode zvinhu, iyo yakakodzera mhando dzakasiyana dzekuchengetedza mabhatiri, masero emafuta, mabhatiri emhepo uye masero ezuva.
Chipanjefuro resimbizvinhu zvinowanzova nezvinhu zvitatu zvinotevera panguva imwe chete: kupisa kwepamusoro, kunyange kana tembiricha inosvika pakunyunguduka kwechigadziko chinokonzera hainyunguduki; panguva imwe chete, ine skeleton yakatsetseka pamusoro uye homogeneous zvinhu, uye isina-porous simbi ine inenge yakafanana inodzivirira kupisa uye anti-oxidation properties; iyo yakavhurika-pore chimiro ine permeability. Iri rudzi rwetitanium furo zvinhu, izvo zvinosanganisa kupisa kwekushisa kwepamusoro, oxidation kuramba uye permeability, inogona kushandiswa kusefa yeguruva pasi pemamiriro ekushisa. Chimiro chakafanana, saizi yekugovera pore idiki, uye kugona kwekuparadzanisa kwakakwira.
